OECD Ten Global Principles for Fighting Tax Crime2020 model

OECD Tax Crime Investigation Maturity Model: self-assessment tool

Self-assess where your jurisdiction stands on the Ten Global Principles for Fighting Tax Crime, and track progress as capability grows.

About the model

What the Tax Crime Investigation model measures

The Tax Crime Investigation Maturity Model helps a jurisdiction see where it stands in implementing the OECD's Ten Global Principles for Fighting Tax Crime, and plan its path to stronger enforcement.

It is also a way to measure progress over time and the impact of capacity-building support. Unlike the tax administration series, it uses four maturity levels, and because the principles depend on each other, weakness in one affects the whole regime.

What is assessed

The 38 elements, by principle

Each element is rated at the level that best describes the administration today. Not every statement under a level has to be met; the aim is the best overall fit, backed by evidence.

Maturity levels

4 levels, from Emerging to Aspirational

The model describes a direction of travel, not a pass mark. There is no single right level for every administration: you choose the target that fits your context, and Nudj measures the gap to it.

Emerging

Some capability to combat tax crime exists, but processes are ad hoc and need significant improvement.

Progressing

Reforms have started, but processes are not yet systematic or institutionalised.

Established

Robust, institutionalised processes give a high degree of capability. Many advanced jurisdictions sit here.

Aspirational

Optimised processes and innovative tools and technology; few jurisdictions are consistently at this level.

How it works in Nudj

From self-assessment to an improvement plan.

Launch

Pick the model from the Nudj library, set the target level, dates and participants.

Discuss

Run the facilitated discussion. Each participant chooses the best-fit level for every attribute.

Evidence

Record the reasons for each rating and attach supporting documents.

Validate

An assessor reviews, challenges and validates the ratings before they count.

Analyse

See the result by attribute and theme, and the gap to your target level.

Act

Turn the gaps into recommendations, a roadmap and owned tasks.

Re-assess

Run the model again later and compare cycles to show progress.

FAQ

Questions about the Tax Crime Investigation model in Nudj

Is this the official OECD Tax Crime Investigation Maturity Model?

Nudj's assessment follows the structure of the OECD Tax Crime Investigation Maturity Model as published by the OECD: the same attributes and the same 4 maturity levels. Nudj is not affiliated with the OECD; we recommend that participants also have the OECD publication to hand.

Can we run the Tax Crime Investigation model as a self-assessment?

Yes. The model is designed as a facilitated self-assessment. Nudj supports a single facilitated session or several respondents rating separately, with an assessor validating the results.

How long does the assessment take?

Designed as a multi-day workshop, with groups each taking one principle.

Can we compare results over time?

Yes. Each run is a separate assessment event, and Nudj compares cycles side by side so you can show progress against your target.

Is Nudj available in Arabic?

Nudj's interface works in English and Arabic, including right-to-left layout. The OECD model content itself is in English.

Can we add our own questions or use other frameworks?

Yes. You can extend a built-in model with your own questions, and use Nudj's framework builder for your organisation's own models alongside the OECD ones.

Why does this model have four levels instead of five?

The Tax Crime Investigation Maturity Model defines Emerging, Progressing, Established and Aspirational, with no Leading level. Nudj scores it on its own four-level scale so results are never measured against a level the model does not define.
